本文档详细介绍了如何在Ubuntu16.04系统上安装IntelGPUOpenCL驱动，并通过编译OpenCV3.4.14来验证驱动的正确安装。首先，从Github下载适用于Ubuntu16.04的OpenCL驱动，并安装deb包。然后，使用clinfo确认驱动安装成功。接着，配置编译环境，下载OpenCV源码并进行编译。最后，编译并运行一个简单的OpenCV程序来检测OpenCL支持。

编译环境

系统环境：Ubuntu 16.04.7 xenial LTS Desktop
CPU：Intel® Core™ i7-6700 CPU @ 3.40GHz

安装Intel GPU OpenCL驱动

在[Github - intel/compute-runtime]上下载支持Ubuntu16.04版本的驱动，我这里下载的版本是18.45.11804，可点击[此处]直接下载对应版本。
此版本支持的CPU架构详情如下：

Platform	OCL	Quality
Broadwell	2.1	Production
Skylake	2.1	Production
Kaby Lake	2.1	Production
Coffee Lake	2.1	Production
Cannon Lake	2.1	Experimental
Apollo Lake	1.2	Production
Gemini Lake	1.2	Production

创建neo目录

mkdir neo # 在磁盘上找个位置，创建一个空的neo文件夹

下载deb安装包

cd neo
wget https://github.com/intel/compute-runtime/releases/download/18.45.11804/intel-gmmlib_18.4.0.348_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/18.45.11804/intel-igc-core_18.44.1060_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/18.45.11804/intel-igc-opencl_18.44.1060_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/18.45.11804/intel-opencl_18.45.11804_amd64.deb

以root权限安装deb包

sudo dpkg -i *.deb

安装clinfo

sudo apt-get install clinfo
